I wonder what Joe Biden thinks of the hilariously irreverent HBO political comedy, “Veep”?

The fab half-hour, starring Julia Louis-Dreyfus in her best role since “Seinfeld,” returns with its glorious ensemble cast skewering White House protocol to fun effect.

This week also brings the end of the increasingly addictive second season of “Dallas” and the promised answer to the question “Who killed J.R.?” It’s also a satisfying way to wish a final fond farewell to the man who made the figure iconic, the late great Larry Hagman.

Veep

9 p.m. Sunday, HBO

TV shows, like politicians, frequently take more risks and shine more brightly in their second terms.

So is the case with the sophomore season of “Veep,” which returns Louis-Dreyfus to her Emmy-winning role of Selina Meyer, the nation’s vice president, who stumbles, schemes and cajoles her way through what she views as a thankless job.

With midterm elections looming, and her approval rating popping up higher than the president’s, however, she throws caution to the wind to boost her influence…with comically disastrous results.

In back-to-back final episodes, viewers get answers not only to “Who killed J.R.?” but also learn exactly what the late oil baron was trying to do before his “masterpiece” was foiled by gunfire.

In the first of two hours, Christopher (Jesse Metcalfe) leaves in search of his mother, the original Pamela, and a piece of news threatens to tear him and Elena (Jordana Brewster) apart.

In the second season finale, the Ewings, led by Bobby (Patrick Duffy) and John Ross (Josh Henderson), seen in photo paying tribute to his dad, unite to execute J.R.’s intended plan. Many shocking twists and turns that would make J.R. smile, are promised.
